At 140 degrees, that is the minimum temperature, whereby any cooler promotes bacterial growth in the food.
The 30 minute road trip promotes additional bacterial growth in the protein rich environment of meat.
Chicken (breast) should be minimally cooked to 160*, with the thighs and legs (dark meat) to 175*, in order to be adequately, and minimally cooked.
